It sounds like a pair (or more) of matrix lines (circuit traces) are
shorted. "Shorted" isn't quite right as it's not a metal-on-metal
connection. With most keyboard circuitry, a dried trail of soda or
coffee can cause this.
I'd put it in the dishwasher, top shelf/face down, std dishwashing
detergent .... shake the hell out of it when it comes out. See what
happens. I've rescued many keyboards that way when the puterstore isn't
open or is too far away.
If that doesn't work, buy a new keyboard.
